About

Who I am, what I do and what I'm curious about.

Backend Developer

Istanbul, Türkiye

Hi, I'm Fatih.

I'm a software developer, mostly drawn to backend systems, databases and software architecture.

At work I build software products on the .NET stack for all kinds of needs. Watching an idea turn into something that actually works is one of my favourite parts of the job.

But my curiosity doesn't stop at software.

I want to know how computers work, what physics sits behind electricity, how technology got to where it is today — and now and then, something completely unrelated. I'd rather get to the bottom of a subject than skim its surface.

That's partly why this site exists: a place to share what I make, explain what I learn and gather the ideas I collect over time.
